Hi, I believe that Linux imposes the following restriction while installing a route. "A gw addr must belong to the same network as the interface on which the route is being set up". Why do we have this restriction? I have seen diagrams (i mean router topologies) showing ASes which are labeled "5.0.0.0/8" and "6.0.0.0/8". The diagram shows that BGP is running on the edge routers. How do these edge routers have routes to each other even though they belong to two different networks (namely 5.0.0.08 and 6.0.0.0/8)? Does the restriction exist in this situation as well? Why or why not?
